Same index. Same holdings. Two tickers, two price tags. QQQ vs QQQM is the simplest comparison in this whole series, which is exactly why people mess it up.
QQQ charges 0.20%. QQQM charges 0.15%. Both hold the Nasdaq-100. This is the kind of thing a fund vs fund comparison tool in 2026 should catch instantly: identical portfolios, cheaper wrapper available, decision made. For a buy-and-hold investor, QQQM is just cheaper. Full stop.
The counterpoint is real though. QQQ launched in 1999 and its options market is deeper and tighter. If you trade Nasdaq-100 options, that liquidity is worth more than five basis points of fee. Traders should stay with QQQ and stop feeling guilty about it. Everyone else is the QQQM customer and has probably been overpaying without knowing.
Five basis points sounds like nothing, I know. On $50,000 over 25 years it's north of a thousand dollars. Free money for picking the cheaper ticker. The lowest expense ratio ETFs aren't automatically the best funds, but when the funds are literally identical, cheapest wins by definition. A best ETF screener app shows the fee gap in about ten seconds, and an ETF comparison database search tool confirms the holdings match line for line. Two minutes of work, years of savings.
One timing wrinkle: if you already hold QQQ in a taxable account, switching means selling, which means taxes. The savings are real but they don't beat a capital gains bill. Get it right on the first buy and you never think about it again.
